Well, that code is focused on extracting data from /dev/urandom ... But yes, if you want to use pwgen(1), you are encouraged to do just that - and if you choose not to do that, beware that any inferior solution - portable or not portable (whatever that means BTW) external program or not - regardless of whatever, that doesn't matter, because if pwgen is superior for its particular purpose then pwgen will still be superior. And I think that's where it stands now. But cheer up Jean, a silver medal at the Olympics isn't that bad! -- underground experts united https://dataswamp.org/~incal
